KRK KNS 8402 Review: how they perform in practice

Customer Review Summary

Introduction

The KRK KNS 8402 over-ear headphones offer a closed-back, circumaural design aimed primarily at studio monitoring and silent instrument practice. Released in October 2021 and priced at £88, they promise a balance between affordability and audio fidelity. This review examines their technical merits, sound profile, comfort, and documented concerns to provide an informed verdict.

Design and Build

The KNS 8402 is engineered with a closed dynamic system and an impedance of 36 Ohms, suitable for use with common audio interfaces and DJ mixers. Weighing just 247 grams (excluding cable), these headphones incorporate memory latex foam padding to enhance comfort during extended sessions. The ear cups are circumaural, fully encompassing the ears to aid noise isolation, complemented by a closed-back construction which limits external sound intrusion.

The headphones come in black and include a detachable cable system. The supplied 2.6 m cable can be extended with a 0.75 m extension that features an integrated volume control, and connectors include a mini-jack with an adapter to a 6.3 mm stereo jack. The package also contains a protective carrying bag and cleaning cloth.

Surface quality and robustness are adequate for the price range, though no luxury materials are used. The rotating ear cups facilitate compact storage and the build feels appropriate for frequent use. Minor issues such as occasional creaking on cup rotation have been noted but are not critical flaws.

Sound Quality

The KRK KNS 8402 delivers a sound signature that aligns with the brand’s reputation in the professional audio market. The frequency response ranges from 10 Hz to 23,000 Hz, ensuring coverage of the spectrum important for monitoring tasks.

• Bass and Low-Mids: The bass is prominent and powerful without overwhelming other frequencies. Some users report a slight boominess, described as “dröhnig,” akin to resonance within a hollow enclosure, indicative of a somewhat colored low end rather than strictly flat clarity.
• Mids: The midrange is accurate and less recessed than often found in budget headphones, providing decent vocal clarity and detail. The signature is considered precise, satisfactorily revealing production details and errors.
• Highs: Treble reproduction is clear, not overly bright or piercing. While some users find the stereo image a bit narrow and somewhat dull, the overall clarity is sufficient for monitoring and casual listening.

The headphones excel at revealing detail within mixes, making them suitable for music production tasks such as digital audio workstation (DAW) monitoring and piano practice without disturbing neighbours. However, their closed nature restricts spatial depth compared to open-back models.

Comfort and Usability

Comfort ranks highly for the KNS 8402 within its price class. The memory foam ear cushions and lightweight build avoid excessive pressure on the ears or head, suitable for prolonged wearing sessions. The over-ear fit is roomy enough to accommodate larger ears and heads, similar in feel to the well-known Sennheiser HD25.

Noise isolation is effective, enabling focused work in noisy environments. The headphones are flexible and adjust easily, with foldable ear cups supporting portability. The removable cable adds versatility but brings its own complications, discussed below.

Cable and Ergonomics Issues

A significant drawback of the KNS 8402 lies with the supplied cable. It is relatively stiff and transmits cable movement noises acoustically through the left ear cup shell, generating disruptive crackles and rubbing sounds during head or body movement. This artefact has been widely reported and can critically impair usability during performance or mixing.

Attempts to mitigate this noise by repositioning the cable are only partially effective. The cable’s mechanical coupling to the ear cup appears inadequately damped, a surprising oversight for headphones designed for studio use. Some users express frustration to the point of returning the product, indicating the cable issue overshadowed otherwise positive attributes.

Durability and Warranty

While the headphones appear solidly constructed, concerns exist regarding the longevity of the synthetic ear pad materials. Reports of premature peeling revealing foam after limited use suggest potential quality or material selection issues. These have surfaced within two years of usage despite the product’s marketed 3-year warranty.

Warranty service experiences have been mixed, with warranty claims for pad degradation often denied based on wear and tear classifications. This has led to suggestions that replacement pads should be anticipated as a routine consumable expense within the first couple of years.

Conclusion

The KRK KNS 8402 headphones offer a compelling package at an accessible price point, with commendable sound quality reflecting KRK’s studio monitor heritage. Their clear mids, controlled highs, and strong bass make them suitable for home studios, music production, and silent practice.

Comfort and noise isolation are adequate for extended wear, and the design’s practicality is enhanced by foldable cups and detachable cabling. Nevertheless, the cable noise issue dramatically affects the listening experience and limits professional use unless an aftermarket cable solution is employed.

Build quality and pad durability meet expectations for the price but may require frequent maintenance or replacement. Buyers should weigh the risk of cable noise and pad wear against their budget and intended application.

, the KRK KNS 8402 is recommended for those seeking a budget closed-back headphone with a studio flavour, provided they can accept or manage the cabling limitations.
